Developer Needed To Finalize Base44 MVP

Project Overview I have built an MVP of an AI-powered SaaS platform using Base44. The application is functional from a frontend/MVP perspective, and I am looking for an experienced full-stack developer to help transform it into a secure, production-ready application. The platform is designed for field service businesses such as HVAC, plumbing, landscaping, electrical, pest control, roofing, and similar industries. Our goal is to create an AI Operations Manager that automates office operations for these businesses.
